To all whom it may concern:

Be it known that I, CARL HERMANN BEIIN- ISCH, manufacturer, residing at Luckenwalde, inthe Kingdom of-Prussia, German Empire, have invented certain new and useful Im-- provements in Machines for Cleaning'TeXtile Fibers, of which the following is a specifica. tion. My invention relates to a feed device for machines for cleaning textile fibers, and more especially for machines' designed to. strip. the fibers from agave-leaves. By means of the new device as many as from twelve to eighteen such leaves canbe automatically and simultaneously fed to the knife-drumand then returned from the same.

Referring to the accompanying'dr'awings, Figure 1 is a side View of the improved do vice; Fig. 2, a plan of the same. Fig. 3 is an enlarged representation of the right-hand upper portion of Fig. 1; and Fig. 4 is a plan of this portion, some parts being left away.

Bearings 1, carried by the frame 2, support the drum 4, which is furnished with a protective ca 3 and with knives 5, serving to remove the fibers from the leaves. Opposite to the drum 4 is located upon the frame 2 a pointed or hook-shaped elastic adjustable displacer 6, which serves for pressing the fibers against the pointed ends of the knives. There are further lateral arms 8 and 9, supporting a shaft 10, earn g chain-wheels 1.1 and 12, rotated from a s aft 13 by means of a worm 14, worm-wheel 15, shaft 16, and bevel-wheels 17 18; also, at the rear end of the frame 2 is a shaft 23, sup orted by arms 21 22 and carrying chaineels 19 20, said shaft being driven from the chain-wheels 11 and 12 by means of two chains 24 25 of equal length. Connected with the chains 24 25 is an endless table consisting of wooden or iron said chains.

Some of the links of the chains 24 25 are noses 28, provided with semicircular recesses 27, arranged one opposite to the other, said noses serving for the rece tion ofya holder 31, W enrotating around the chain-wheels, the noses 28 separate, Fig. 3, and afterwardthat is to say, when the motion of the chains is again rectilinealthey regain their former position. In. order to prevent the holder from leaving the chains at that end of the machine-where there-are the knives, circular guide-rails are provided upon which the pivots 29 30 glide.

To fix the agave-leaves A after being inserted'into the holder 31, I prefer to employ an eccentric press 32, actuated in well known manner by a lever system 34, operated by foot-pressure, the treadle, however, not being shown on the drawings. The jaws of the holder 31 being thus closed by the press, the thumb-screw 33 must be tightened to hold them together. Instead of the .press and thumb-screw any other suitable means may of course be employed.

The machine operates as follows: First the empty holder 31 is inserted into the press 32 an then the agave-leaves are put into the holder. This latter is then closed by the foot being applied to the treadle. Thereupon the thumb-screw 33 is tightened. The

holder, with the leaves,is now placed between two of the opened or separated noses 28 and transported by them automatically toward the'rotating knife-drum. First the pointed ends of the leaves and then the leaves themselves are operated by the knives, and after that they are slowly withdrawn from the drum with and by the holder until they are finally taken out of the same.

' Having described my invention, I claim as new" 1. In a machine for cleaning textile fibers,

a knifedrum, a feed device, comprising parallel endless traveling chains located in front of the knife-drum and presenting pairs of jaws; means for supporting and for driving the chains; an apron carried by the chains; and a fiber-holder gripped by the said jaws and carried along by the chains; substantially as described.

2. In a machine for cleaning textile fibers, a knife-drum, a feed device, comprising parallel endless traveling chains located in front of the knife-drum and presenting pairs of jaws; means for supporting and for driving the chains; an apron carried by the chains; a fiber-holding clamp gripped by the said jaws and carried along by the chains; and means for guiding the clamp; substantially as described.

In testimony whereof I have hereunto set my hand in presence of two witnesses. CARL HERMANN BEHNISCH. Witnesses:
